Description

Technical Field

[0001] The present invention relates to the technical field of home intelligent production, and particularly relates to an automatic palletizer for home appliance finished products. Background Art

[0002] Household appliances refer to various electrical and electronic appliances used in families and similar places. In the logistics process of household appliance production, large household appliances such as refrigerators and televisions need to be filled with buffer materials such as foam pads in the packaging boxes, and then stacked layer by layer after being suspended and transported by a robotic arm. During the palletizing process, due to the inertial effect generated when the robotic arm starts and stops, the household appliances squeeze the buffer materials, resulting in the shaking phenomenon of the household appliances during moving and palletizing. At the same time, due to the soft shock-absorbing characteristics of the buffer materials and the box body, when the robotic arm releases the packaging box and it lands on the pallet, there will be a bouncing phenomenon, which affects the stability of the household appliance finished products during palletizing and reduces the working efficiency of palletizing the household appliance finished products.

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0017] An automatic household appliance finished product palletizer, including a main body 1, a robotic arm 11 rotatably connected to the top surface of the main body 1, a manipulator 12 rotatably connected to the front end of the robotic arm 11, and a mounting rod 13 detachably connected to the front end of the manipulator 12. Above the mounting rod 13, a motor 14 is detachably connected to the top surface of the manipulator 12. The bottom surface of the mounting rod 13 is fixedly connected to a top plate 2. The bottom surface of the top plate 2 is fixedly connected to guide blocks 21, and the guide blocks 21 are symmetrically arranged. The front side surface of the top plate 2 is fixedly connected to a positioning plate 22. Symmetric guide rods 23 are arranged at the top of the positioning plate 22. One end of the guide rod 23 penetrates through the positioning plate 22 and the guide block 21 and extends to the outside of the rear side of the top plate 2. The other end of the guide rod 23 is detachably connected to a placing plate 24. The bottom surface of the placing plate 24 is fixedly connected with a plurality of placing rods 25. Above the positioning plate 22, symmetric telescopic cylinders 26 are fixedly connected to the upper surface of the top plate 2. A fixing mechanism 3 for clamping the front and rear sides of the box body is arranged between the guide blocks 21 on the bottom surface of the top plate 2. A tilt mechanism 4 for tilting the box body and assisting the placing rod 25 to move to the bottom surface of the box body is arranged below the fixing mechanism 3 on the bottom surface of the top plate 2.

[0018] As Figure 1As shown in the figure, the main body 1 is fixedly connected to the factory floor by bolts. A robotic arm 11 is rotatably connected to the upper surface of the main body 1, and a robotic hand 12 is rotatably connected to the front end of the robotic arm 11. The front side of the robotic hand 12 is detachably connected to a mounting rod 13, and the bottom surface of the mounting rod 13 is fixedly connected to the top plate 2. The motor 14 is detachably connected to the top surface of the robotic hand 12, and the rotating rod of the motor 14 is detachably connected to the top surface of the mounting rod 13. The mounting rod 13 can rotate inside the robotic hand 12. Therefore, the motor 14 can drive the top plate 2 to rotate through the mounting rod 13. At the same time, the main body 1, the robotic arm 11, and the robotic hand 12 cooperate with each other to drive the box below the top plate 2 to be suspended and transported from the starting position to the specified palletizing position. As Figure 1 - Figure 2 shown and Figure 4 shown, a guiding block 21 is fixedly connected to the bottom surface of the top plate 2. The guiding blocks 21 are symmetrically arranged. The front side surface of the guiding block 21 and the front side surface of the top plate 2 are fixedly connected to the rear side of the top of the positioning plate 22. One end of a guiding rod 23 passes through the positioning plate 22 and the guiding block 21 and extends to the outside of the rear side of the top plate 2. The other end of the guiding rod 23 is detachably connected to a placing plate 24. Multiple placing rods 25 are fixedly connected to the inner side of the bottom of the placing plate 24. The multiple placing rods 25 are evenly distributed. The placing plate 24 and the multiple placing rods 25 can form an L-shaped structure to support the bottom surface of the box. At the same time, a telescopic cylinder 26 is fixedly connected to the upper surface of the top plate 2 above the positioning plate 22. The telescopic cylinders 26 are symmetrically arranged. The front end of the piston rod of the telescopic cylinder 26 is detachably connected to the top surface of the placing plate 24. Therefore, when the telescopic cylinder 26 is started, the placing plate 24 can move closer to or away from the positioning plate 22, and the placing rods 25 move synchronously with the placing plate 24. The guiding rod 23 moves inside the positioning plate 22 and the guiding block 21 to improve the stability of the movement of the placing plate 24.

[0019] As Figure 1 - Figure 3 shown, the fixing mechanism 3 includes a gear 31 rotatably connected to the bottom surface of the top plate 2. The gear 31 is located on the vertical axis of the bottom surface of the top plate 2. A first rack 32 and a second rack 33 are symmetrically arranged on the left and right sides of the gear 31. The first rack 32 is slidably connected to the inside of the guiding block 21 on the left side of the gear 31, and the second rack 33 is slidably connected to the inside of the guiding block 21 on the right side of the gear 31. Both the first rack 32 and the second rack 33 are meshed with the gear 31. As Figure 1 - 4 shown and Figure 6 shown, a notch is formed at the top of the moving plate 34. At the same time, a notch is also formed at the top of the positioning plate 22. There are two such notches and they are symmetrically arranged left and right. The notch on the left side of the positioning plate 22 and the notch on the moving plate 34 are on the same straight line to assist the front and back movement of the first rack 32. The notch on the right side of the positioning plate 22 is used to assist the front and back movement of the second rack 33. As Figure 1 - Figure 4As shown in the figure, the front side of the first rack 32 penetrates through the left slot of the positioning plate 22 and is detachably connected to the inner side of the top of the placement plate 24. The rear side surface of the second rack 33 is fixedly connected with a moving plate 34. The front side of the second rack 33 corresponds to the right slot of the positioning plate 22. Among them, the top surface of the moving plate 34 is slidably connected to the bottom surface of the top plate 2. The placement plate 24 drives the first rack 32 to move towards the rear side of the top plate 2. The first rack 32 pushes the gear 31 to rotate, so that the gear 31 drives the moving plate 34 to move towards the front side of the top plate 2 through the second rack 33, thereby reducing the distance between the moving plate 34 and the positioning plate 22, so that the front and rear sides of the box body are clamped by the moving plate 34 and the positioning plate 22.

[0020] As Figure 3 - Figure 4 shown in the figure, the bottom surface of the gear 31 is rotatable on the upper surface of the support rod 35. The front side of the support rod 35 is fixedly connected to the inner side of the positioning plate 22, and the rear side of the support rod 35 is fixedly connected to the rear side of the top plate 2. A slot is opened at the top of the moving plate 34 between the first rack 32 and the second rack 33. The moving plate 34 can slide along the outer surface of the support rod 35 through the slot to support the moving plate 34 and improve the stability of the movement of the moving plate 34.

[0021] As Figure 5 - Figure 8 shown in the figure, the tilting mechanism 4 includes a fixed bracket 41 detachably connected to the front side of the upper surface of the top plate 2. The shape of the fixed bracket 41 is set to be L-shaped. The top of the fixed bracket 41 is fixed to the upper surface of the top plate 2 by bolts. There are two fixed brackets 41 and they are symmetrical. A first rod 42 is fixedly connected between the bottoms of the fixed brackets 41. A first rotating plate 43 is rotatably connected to the outer surface of the first rod 42 inside the bottom of the fixed bracket 41. There are two first rotating plates 43 and they are symmetrical. A support rod is fixedly connected to the bottom of the first rotating plate 43. A first pressing wheel 44 is rotatably connected to the inner side of the end of the support rod. As Figure 3 - Figure 4 and Figure 7 shown in the figure, a first plate 45 is fixedly connected to the top of the first rotating plate 43. The first plate 45 is located above the first rod 42. Symmetrical convex blocks 46 are fixedly connected to the upper surface of the first plate 45. A groove 47 is opened inside the convex block 46. A second rod 48 is fixedly connected to the inner side of the top of the convex block 46. A rotating rod 49 is rotatably connected to the end of the second rod 48. Protruding rods are fixedly connected to the top and bottom of the rotating rod 49. The protruding rod at the bottom of the rotating rod 49 is fitted into the groove 47. At the same time, a chute 27 is opened at the bottom of the guide block 21. The width of the chute 27 is smaller than the diameter of the guide rod 23. The protruding rod at the top of the rotating rod 49 extends into the chute 27. A push block 28 is fixedly connected to the bottom of the guide rod 23 inside the chute 27. The push block 28 is fitted with the protruding rod at the top of the rotating rod 49. As Figure 3 - Figure 8As shown, the top plate 2 moves above the box body on the upper surface of the stacking plate. The tilting mechanism 4 and the auxiliary mechanism 5 are symmetrical and located on the front and rear sides of the top of the box body. During the movement of the placing plate 24, the guiding rod 23 pushes the protruding rod at the top of the rotating rod 49 through the pushing block 28. The rotating rod 49 rotates around the second rod 48, and the protruding rod at the bottom of the rotating rod 49 squeezes the convex block 46 through the groove 47, so that the convex block 46 drives the first rotating plate 43 to rotate around the first rod 42 through the first plate 45. Thus, the first rotating plate 43 drives the first pressing wheel 44 to push the front side of the top of the box body obliquely upward through the support rod. Since the auxiliary mechanism 5 abuts against the rear side of the top of the box body, the entire box body can tilt around the rear end of the bottom of the box body towards the rear side of the top plate 2, so that an included angle area is formed between the bottom surface of the box body and the upper surface of the stacking plate. After the front end of the placing rod 25 extends into the included angle area, the pushing block 28 disengages from the protruding rod at the top of the rotating rod 49, and the first pressing wheel 44 releases the extrusion on the front side of the top of the box body. At this time, the moving plate 34 contacts the rear surface of the box body. As the placing plate 24 moves, with the assistance of the moving plate 34, the box body is moved onto the upper surface of the placing rod 25. The placing rod 25 supports the bottom surface of the box body, and the moving plate 34 and the positioning plate 22 limit the front and rear sides of the top of the box body, thereby reducing the shaking of the box body during movement. At the same time, when the box body is placed on the stacking plate, during the resetting process of the placing plate 24, the placing plate 24 makes the moving plate 34 and the positioning plate 22 release the limit on the front and rear sides of the box body through the first rack 32, and the pushing block 28 pushes the rotating rod 49 to rotate in the reverse direction and does not contact the convex block 46.

[0022] As Figure 5 - Figure 8 shown, the auxiliary mechanism 5 includes a movable bracket 51 detachably connected to the rear side of the upper surface of the top plate 2. The movable bracket 51 includes an outer plate and an inner plate. The top of the outer plate is detachably connected to the upper surface of the top plate 2, and the top of the inner plate is slidably connected to the bottom surface of the guiding block 21. The bottom of the outer plate and the bottom of the inner plate are fixedly connected by a fifth rod 52. A second rotating plate 53 is rotatably connected to the surface of the fifth rod 52 on the inner side of the outer plate, and a second rotating plate 53 is also rotatably connected to the surface of the fifth rod 52 on the inner side of the inner plate. The second rotating plates 53 are symmetrically arranged on the fifth rod 52. The second rotating plate 53 is provided with two support rods. One support rod is located at the front of the second rotating plate 53, and the other support rod is located at the bottom of the second rotating plate 53. Among them, a second pressing wheel 54 is rotatably connected between the front support rods of the second rotating plate 53, and the bottom support rods of the second rotating plate 53 are connected by a connecting rod 55 to improve the structural strength of the movable bracket 51; As Figure 6 - Figure 7As shown in the figure, the outer side of the bottom of the first rotating plate 43 is connected to the outer side of the bottom of the second rotating plate 53 through a linkage device 6. The linkage device 6 includes rotating heads 61. There are two rotating heads 61. One rotating head 61 is rotatably connected to the outer side of the bottom of the first rotating plate 43, and the other rotating head 61 is rotatably connected to the outer side of the bottom of the second rotating plate 53. The rotating heads 61 are connected by a third rod 62 and a fourth rod 63. When the first rotating plate 43 rotates, the second rotating plate 53 can be driven to rotate through the rotating heads 61, the third rod 62 and the fourth rod 63, so that the front strut of the second rotating plate 53 drives the second pressing wheel 54 to press downward on the rear side of the top of the box body, cooperating with the first pressing wheel 44 to assist the box body to be inclined. The first pressing wheel 44 and the second pressing wheel 54 can be made of rubber material to reduce the damage to the box body caused by extrusion. As Figure 6 - Figure 7 shown in the figure, the surface of the third rod 62 is provided with a threaded groove, the inside of the fourth rod 63 is a cavity, and the inner wall of the cavity is also provided with a threaded groove and is fitted with the third rod 62. At the same time, the third rod 62 is rotatably connected to the rotating head 61, and the fourth rod 63 is fixedly connected to the rotating head 61. It should be noted that it can also be set that the fourth rod 63 is rotatably connected to the rotating head 61, and the third rod 62 is fixedly connected to the rotating head 61. As Figure 7 shown in the figure, so when the third rod 62 is rotated, the front end of the third rod 62 continuously extends into or out of the cavity of the fourth rod 63, thereby reducing or increasing the length of the third rod 62. At the same time, a plurality of installation grooves 64 are provided on the upper surface of the top plate 2 above the movable support 51, and the installation grooves 64 are fitted with the end of the top of the outer plate. Therefore, by changing the length of the third rod 62 and the position of the end of the top of the outer plate, the tilting mechanism 4 and the auxiliary mechanism 5 can be adapted to boxes of different lengths. As Figure 3 - Figure 4 shown in the figure, at the same time, a rotating rod is provided at the center of the gear 31. A plurality of positioning holes 65 are provided on the upper surface of the support rod 35, and the plurality of positioning holes 65 are evenly distributed. The top of the positioning hole 65 extends to the bottom surface of the top plate 2, and the positioning hole 65 on the bottom surface of the top plate 2 is fitted with the top of the rotating rod. The positioning hole 65 on the upper surface of the support rod 35 is fitted with the bottom of the rotating rod. The gear 31 rotates between the upper and lower positioning holes 65 through the rotating rod, and the top and bottom of the rotating rod can be telescopic. Therefore, the gear 31 can be adjusted between the positioning holes 65 at different positions to make the gear 31 engage with different positions of the first rack 32, so as to adjust the effective moving distance of the second rack 33 through the first rack 32, and limit the front and rear sides of boxes of different lengths by the moving plate 34 and the positioning plate 22.

[0023] As Figure 1 - Figure 2 and Figure 5As shown in the figure, a limiting rod 72 can also be arranged on the upper surface of the placing plate 24. The limiting rods 72 are symmetrically arranged. A limiting groove 7 is formed inside the bottom of the placing plate 24. A sliding rod 71 is fixedly connected between the left and right sides of the limiting groove 7. The front end of the limiting rod 72 is slidably connected to the outer surface of the sliding rod 71. A return spring 73 is sleeved on the outer surface of the sliding rod 71 between the right side of the limiting rod 72 and the right side of the limiting groove 7. The front side of the limiting rod 72 expands outwards and a moving block 74 is fixedly connected to the bottom surface at the corner. A connecting plate 75 is arranged horizontally and is connected with a plurality of placing rods 25. A groove 47 is formed on the upper surface of the connecting plate 75. The moving block 74 is slidably connected inside the groove 47. With the assistance of the moving plate 34, the box body is pushed onto the upper surface of the placing rod 25, so that the left and right sides of the bottom of the box body are limited by the limiting rods 72, further reducing the shaking of the box body during movement. And the limiting rods 72 can move above the placing rods 25. Under the action of the return spring 73, the limiting rods 72 can fix box bodies of different sizes.

[0024] It should be noted that the present invention is an automatic palletizing machine for finished household appliances. As Figure 1 - Figure 8 shown, during use, the robotic arm 11 moves the top plate 2 above the box body through the manipulator 12 and the mounting rod 13, so that the tilting mechanism 4 and the auxiliary mechanism 5 are located on the front and rear sides of the top of the box body. The telescopic cylinder 26 drives the placing plate 24 to move, so that the guide rod 23 drives the rotating rod 49 to rotate through the push block 28. Thus, the rotating rod 49 drives the first rotating plate 43 to rotate through the convex block 46. The first pressing wheel 44 pushes the front side of the top of the box body obliquely upwards. At the same time, the auxiliary mechanism 5 abuts against the rear side of the top of the box body. And under the action of the third rod 62 and the fourth rod 63, the second pressing wheel 54 presses down on the rear side of the top of the box body, so that the whole box body can tilt around the rear end of the bottom of the box body towards the rear side of the top plate 2, thereby forming an included angle area between the bottom surface of the box body and the upper surface of the pallet. Then the placing plate 24 drives the front end of the placing rod 25 to extend into the included angle area. At the same time, the placing plate 24 moves through the first rack 32. The first rack 32 drives the second rack 33 to move through the gear 31. Thus, the moving plate 34 approaches the positioning plate 22. And the push block 28 is separated from the rotating rod 49. The first pressing wheel 44 and the second pressing wheel 54 are released. With the assistance of the moving plate 34, the box body is moved onto the upper surface of the placing rod 25. The placing rod 25 supports the bottom surface of the box body. And the moving plate 34 and the positioning plate 22 limit the front and rear sides of the top of the box body, thereby reducing the shaking of the box body during movement. Then the robotic arm 11 drives the box body to be placed on the pallet. The placing plate 24 resets and releases the limitation on the front and rear sides of the box body by the moving plate 34 and the positioning plate 22 through the first rack 32. Blocked by the positioning plate 22, the placing rod 25 is drawn out from the bottom of the box body, thereby placing the box body stably on the upper surface of the pallet, reducing the phenomenon of the box body bouncing up and improving the stability of the box body during palletizing.
